Creating Adaptive Launcher Icons with Flutter
Getting Started
Before creating adaptive launcher icons, make sure you have an image ready for your icon. The recommended size is 1024×1024 pixels, but you can use any size as long as it’s a 1:1 ratio. Create a directory in your Flutter app called assets and move your icon image into it.
Adding flutter_launcher_icons to Your Project
In your pubspec.yaml file, add flutter_launcher_icons under dependencies. You’ll also need to add the flutter_icons property to specify the path to your icon image.
dependencies:
flutterlaunchericons: ^0.9.3
flutter_icons:
image_path: assets/icon.png
Configuring Adaptive Icons
To create adaptive icons, you’ll need to specify additional properties in your pubspec.yaml file. For example, you can specify a different image path for Android and iOS using the image_path_android and image_path_ios properties.
flutter_icons:
image_path: assets/icon.png
image_path_android: assets/icon_android.png
image_path_ios: assets/icon_ios.png
Using Adaptive Icon Layers
Adaptive icons can consist of two layers: a foreground and a background. To specify these layers, you can use the adaptive_icon_foreground and adaptive_icon_background properties.
flutter_icons:
image_path: assets/icon.png
adaptive_icon_foreground: assets/icon_foreground.png
adaptive_icon_background: assets/icon_background.png
Platform-Specific Considerations
When creating adaptive icons, you’ll need to consider platform-specific requirements. For example, iOS requires icons to be opaque, while Android allows for transparent icons. To address these differences, you can use platform-specific properties in your pubspec.yaml file.
flutter_icons:
image_path: assets/icon.png
ios: true
image_path_ios: assets/icon_ios.png
Troubleshooting Common Issues
When working with flutter_launcher_icons, you may encounter issues such as minSdkVersion conflicts or style inconsistencies. To resolve these issues, refer to the package documentation and community forums for solutions and workarounds.
